Sandvik 12C27™ is our main knife steel for hand-held knives, high-end ice skate blades and ice drills. Continuous improvement over a period of 45 years has evolved it into the high performing steel grade it is today. The composition is tighter, the purity level is much higher and the fine carbide microstructure of today is far from how Sandvik 12C27™ knife steel of the sixties looked.
